Would it be possible to use your complete name for your contributions?

Please add an empty line here, followed by the URL of the upstrealm
project. It can be just a link to the homepage of the Github project.

Please use the "github" function available in Buildroot. See the
documentation and the numerous other examples in Buildroot (you can
grep for "call,github").

Also, please add a hash file for this package.

> +LIBAMCODEC_LICENSE = GPL

This should be more specific: GPLv2, GPLv2+, GPLv3, GPLv3+.

Also, please add a value for <pkg>_LICENSE_FILES.

Can you use $(TARGET_CONFIGURE_OPTS) instead of CC=... LD=... ?

PREFIX=$(STAGING_DIR)/usr is not correct, it should be PREFIX=/usr,
because once on the target, things will be in /usr.

Also, why is the PREFIX needed at build time?

Other than that, looks good.

Thanks!
